Description

Technical Field

[0001] This utility model belongs to the field of chemical pump technology, specifically an offline testing device for chemical pumps. Background Technology

[0002] Chemical pumps, as core conveying equipment in chemical production processes, are widely used in petrochemical, pharmaceutical, and metallurgical chemical industries. In modern chemical production, chemical pumps play a circulatory role in the chemical process, much like the heart pumps blood to the body; they deliver various process media throughout the plant.

[0003] After a chemical pump is repaired, its performance must be verified and tested to ensure that it can be reinstalled and used after normal operation. However, when verifying a chemical pump, it must be fixed on a mounting base to complete the verification and testing.

[0004] In the existing technology, the mounting holes of the fixed seat correspond one-to-one with the mounting holes of the chemical pump. When fixing, the mounting holes of the chemical pump are aligned with the mounting holes of the fixed seat, and bolts are passed through the mounting holes and the fixing holes to complete the fixing.

[0005] However, the mounting holes on the mounting base correspond one-to-one with the mounting holes on the base of the chemical pump. The positions of the mounting holes will change for different models of chemical pumps. However, different models of chemical pumps require special mounting bases, and workers need to frequently replace the mounting bases. Due to the poor versatility of the mounting bases, this not only increases the labor intensity of workers and consumes a lot of time and manpower, but also affects work efficiency. Utility Model Content

[0006] The purpose of this invention is to solve the above-mentioned problems and provide an offline testing device for chemical pumps. This device fixes one connecting rod and makes the other sliding. The connecting rod is equipped with studs and adjustable threaded column assemblies, so that each stud and each threaded column assembly can correspond one-to-one with the position of the mounting hole, thereby enabling the fixing of chemical pumps of the same model with high compatibility.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1

[0032] refer to Figures 1-3 An offline testing device for a chemical pump includes a fixed base 1 and a testing mechanism 2 for testing the pressure at the inlet and outlet of a chemical pump 6. The testing mechanism 2 is detachably connected to the inlet and outlet of the chemical pump 6. The base 61 of the chemical pump 6 has multiple mounting holes (not shown in the figure) and also includes two connecting rods 3 arranged side by side.

[0033] One of the connecting rods 3 is fixed to the fixed base 1, and the other connecting rod 3 is slidably connected to the fixed base 1. The connecting rod 3 slidably connected to the fixed base 1 can slide towards or away from the other connecting rod 3.

[0034] Both connecting rods 3 are fixedly connected to the top of a stud 31, and both connecting rods 3 are provided with a threaded post assembly 5. All threaded post assemblies 5 can be adjusted in position along the length direction of their corresponding connecting rods 3. The stud 31 and threaded post assembly 5 are used to lock the base 61 with a nut after passing through the corresponding mounting hole.

[0035] The chemical pump 6 has been disclosed in Chinese patent CN 221973820U, so the structure of the chemical pump 6 will not be described in detail in this embodiment.

[0036] In this design, workers can first lift the chemical pump 6 to the top of the fixed base 1 using a gantry crane or manually. Then, according to the position of the mounting holes on the base 61, the sliding connecting rod 3 is slid closer to or further away from another connecting rod 3, so that the stud 31 can first correspond to the position of two of the mounting holes. Next, the positions of the two threaded column assemblies 5 are adjusted so that the two threaded column assemblies 5 can correspond to the position of the remaining mounting holes. Then, the chemical pump 6 is slowly lowered vertically so that each stud 31 and each threaded column assembly 5 can pass through the corresponding mounting hole. Then, the nut is connected to the stud 31 and the threaded column assembly 5 to lock the base 61. Next, the detection mechanism 2 is connected to the inlet and outlet of the chemical pump 6 for detection. After the detection is completed, the detection mechanism 2 is separated from the inlet and outlet of the chemical pump 6. Then, the nut connected to the stud 31 and the threaded column assembly 5 is removed, and the chemical pump 6 is removed. In this way, different models of chemical pumps 6 can be used, improving the compatibility of the base 61.

[0037] In this embodiment, the fixing base 1 has a rectangular structure, and the fixing base 1 is provided with two T-shaped guide rails 11 arranged side by side. The length of the T-shaped guide rails 11 extends along the width direction of the fixing base 1.

[0038] The length of the connecting rod 3 extends along the length direction of the fixed base 1. Both ends of the connecting rod 3, which is slidably connected to the fixed base 1, are provided with T-slots 33. The T-slots 33 correspond one-to-one with the T-shaped guide rails 11. The connecting rod 3, which is slidably connected to the fixed base 1, slides with the T-shaped guide rails 11 through its T-slots 33.

[0039] Furthermore, the two connecting rods 3 are respectively Figure 2 3a and 3b are in the middle. 3a is fixed and can be fixed to the fixed base 1 by bolt 12 or welding. Since T-slots 33 are set at both ends of the connecting rod 3, 3b can be slidably adjusted by the cooperation of T-slots 33 and T-slot guide rail 11.

[0040] In this embodiment, the threaded column assembly 5 is positionally adjusted by an adjustment structure 4; both connecting rods 3 have the adjustment structure 4.

[0041] The adjustment structure 4 includes a support rod 42 and two plates 41. Both plates 41 are fixedly connected to one side of the connecting rod 3. The support rod 42 is connected between the two plates 41. The length of the support rod 42 extends along the length direction of the connecting rod 3. The threaded column assembly 5 is slidably connected to the support rod 42.

[0042] The threaded column assembly 5 includes an L-shaped block 51 and a threaded column 52;

[0043] The L-shaped block 51 includes a vertical section 511 and a horizontal section 512 connected to the vertical section 511. The vertical section 511 is provided with a through hole, and the vertical section 511 is slidably connected to the support rod 42 through the through hole. The threaded post 52 is provided on the top of the horizontal section 512.

[0044] Specifically, the length of the base 61 and the position of the mounting hole are different for different models of chemical pumps 6; the L-shaped block 51 can be moved on the support rod 42, so the position of the threaded column 52 can be adjusted by sliding the L-shaped block 51, so that the position of the threaded column can be aligned with the position of the mounting hole after adjusting the position of the L-shaped block 51.

[0045] Preferably, the support rod 42 has a cylindrical structure, and the through hole has a circular structure;

[0046] A vibration damping pad 53 is provided on the side of the horizontal section 512 facing away from the threaded column 52. The vibration damping pad 53 can be made to fit against the top of the connecting rod 3 by swinging the L-shaped block 51.

[0047] The top of the connecting rod 3 is provided with a fixing plate 32, and the stud 31 is provided on the top of the fixing plate 32.

[0048] In a preferred embodiment, the fixing plate 32 is welded to the connecting rod 3, and the stud 31 is also welded to the fixing plate 32. Generally, the thickness of the fixing plate 32 is equal to the sum of the thickness of the horizontal section 512 and the damping pad 53. The damping pad 53 can be fixed by adhesive. The support rod 42 has a cylindrical structure and a circular through hole, so the L-shaped block 51 can swing. By swinging, the damping pad 53 can be attached to the top of the connecting rod 3. In this way, when verifying and testing the chemical pump 6, vibration can be reduced by the damping pad 53. Moreover, by swinging, the wear on the damping pad 53 is reduced when adjusting the position of the L-shaped block 51.

[0049] Preferably, it also includes two bolts 12, which are screwed onto the fixed seat 1. The bolts 12 correspond one-to-one with the T-shaped guide rails 11. The T-shaped guide rails 11 are located between the bolts 12 and the connecting rods 3 fixed to the fixed seat 1. The bolts 12 are used to prevent the sliding connecting rods 3 from disengaging from the T-shaped guide rails 11.

[0050] More preferably, the support rod 42 is located on the opposite side of the two connecting rods 3. This makes it easier for workers to adjust the position of the L-shaped block 51.

[0051] Preferably, the detection mechanism 2 includes a liquid storage tank 21, a first pressure sensor (not shown in the figure) and a second pressure sensor (not shown in the figure). The liquid storage tank 21 is provided with an inlet pipe 22 and an outlet pipe 23. The inlet pipe 22 is connected to the outlet of the chemical pump 6 through a first flange 221, and the outlet pipe 23 is connected to the inlet of the chemical pump 6 through a second flange 231. The first pressure sensor is installed on the outlet pipe 23, and the second pressure sensor is installed on the inlet pipe 22.

[0052] Specifically, the chemical pump 6 circulates the liquid in the storage tank 21. During this circulation process, the first pressure sensor monitors the liquid pressure in the outlet pipe 23 in real time, and the second pressure sensor detects the pressure value in the inlet pipe 22 simultaneously. By comparing the pressure data obtained by the two pressure sensors, the chemical pump 6 is tested and verified.

[0053] After verification is completed, first disassemble the first flange 221 and the second flange 231, and then remove the nuts connected to the threaded column assembly 5 and the stud 31 before removing the chemical pump 6.

[0054] Preferably, the stud 31 is located at the end of the connecting rod 3 near the detection mechanism 2. The stud 31 is fixed, which makes it convenient for workers to first align two of the mounting holes with the stud 31 one by one, then adjust the position of the threaded stud assembly 5, and then connect the detection mechanism 2 and the inlet and outlet of the chemical pump 6.

[0055] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements or modifications can be made without departing from the principle of the present utility model, and these improvements or modifications should also be considered within the protection scope of the present utility model.
